The science

It doesn't kill them.
It carries them out.

Every rinse on the shelf cleans by killing, good bacteria and bad. This one kills nothing. Here is how it works.

Where it starts

Not on the tooth.
Under the gum.

Gum disease begins in the pocket where gum meets tooth. About 4mm deep when healthy, deeper when not.

  • A brushstops where the gum begins.
  • Flossgoes between teeth, not down.
  • A rinsesheets away over the top.

The mechanism

Penetrate · Bind ·
Extract.

Oil and water don't mix. That's why this reaches where a rinse can't.

01

Penetrate

Pre-liquified, so it flows into the pocket instead of beading at the opening.

02

Bind

The sticky film is fat-soluble. It grips the oil, like flour on oily fingers.

03

Extract

You spit. The film leaves inside the oil. Good bacteria stay put.

The flour test

Try it on your own hands.
You already know how it ends.

Floured fingers under the tap. Then again with a drop of oil. Same physics, 4mm under your gum.

It runs straight past.

The powder stays. Adding antiseptic changes what it kills, not where it reaches.

It picks the film up and leaves.

Nothing was killed. It was carried out.

The evidence

Six trials.
One conclusion.

2023Meta-analysis

Plaque and gingivitis down as much as with chlorhexidine, without its side effects.

Jong, Ooi & Teoh
2020Scientific Reports

Seven days of chlorhexidine shifted the mouth's bacterial balance.

Bescos et al.
2011In vitro mechanism

It works physically, by emulsifying and binding. Not by killing.

Asokan et al.
2009Triple-blind RCT

Gingivitis scores significantly lower than control in two weeks.

Asokan et al.
2008Triple-blind RCT

Decay bacteria counts down from two weeks of daily use.

Asokan et al.
2011Randomised pilot

Bad-breath markers down, self-reported and measured.

Asokan et al.

We didn't run any of these. That's rather the point.

Why you finish it

The honest part

What this does,
and what it never will.

Most brands only publish one column. We publish both.

We do not claim

Things it cannot do

  • Regrow gum tissue

    Receded gum doesn't come back. Nothing can do that.

  • Reverse a cavity

    It helps early surface loss. A hole needs a dentist.

  • Treat periodontal disease

    Use it alongside treatment, with your dentist's knowledge.

  • Replace brushing or floss

    It reaches where they can't. It doesn't replace them.

The evidence supports

Things it does

  • Reduce plaque and gingivitis scores

    Against controls, in randomised trials.

  • Lower decay and bad-breath bacteria

    Measured in plaque and saliva.

  • Leave your good bacteria alone

    Because nothing is killed.

  • Feel comfortable enough to keep doing

    No sting, no burn.

Now you know
as much as we do.
Give it a fair month.

Use it for thirty days. If nothing has changed, we refund you in full and you keep the product.
